Factor in:
Displacement to Length ratio i.e. is your yacht relatively light or heavy for her length ? 
Anticipated anchoring conditions e.g. depth, seabed holding characteristics, the length of fetch and degree of exposure to prevailing winds (worst case scenario)
Weight and design of your bower (main anchor) and also the specification of your secondary anchoring system

An Anchoring System includes every part of the anchor rode from the anchor to the bitter end: anchor, chain, warp and all the individual means of joining it all together e.g.  connectors; swivels; shackles; splicing
All the individual parts need to be comparable in strength. The Anchor System is only as strong as the weakest link
The increased holding power of modern anchors means that all the joining elements are subjected to higher loads than ever before

A second (kedge) anchoring system is generally recommended in addition to the full specification primary (bower) system.
The specification can vary widely according to cruising intentions - from a full specification second storm anchoring system to a traditional Kedge e.g. lunch hook or stern anchor
Different anchors have varying degrees of holding power according to the seabed, so the option of a geometrically different anchor may be advantageous if the primary system is not holding
Traditionally, a second anchor system has less chain, more rope and a lighter stowable anchor - making the whole system physically easier to store on board and deploy when required.
